Described below are procedures for ensuring the accuracy, durability, and correct use of your Anritsu Meter temperature measuring product.

Tolerance

The thermocouples used in Anritsu Meter products comply with the Class 2 tolerance standards specified within the Japanese Industrial Standard JIS C1602-2015.
However, since probes structure and other factors can affect the tolerance of specific temperature measuring probes, please refer to the pertinent pages for information on the precision of specific probes.

The tolerance of surface probes can vary significantly depending on measuring conditions, measurement target, and the nature of the contact between the probe and measurement target.When using a probe, make sure the sensor head correctly contacts target surface.

The probe product pages use the following symbols to indicate probe durability.Note that probe durability can vary significantly depending on actual conditions of use.

Stationary Surface Temperature probes

Number of contacts enabling measurement within the accuracy range on a flat and smooth metal surface at a temperature of 300°C(or at the operating temperature limit if the operating temperature limit is below 300°C).

Moving / Rotating Surface Temperature probes

Time period in which measurement was achieved within the accuracy range, on a flat and smooth metal surface moving at a rate of 200 m/min.

Liquid or Gas Temperature probes

When used correctly, virtually no deterioration occurs in these products due to temperature measuring operations.Therefore, the durability ranking is based on the ease with which impact results in damage.

Operating temperature limit

The operating temperature limit is determined by the allowable temperature limit of the sensor head contacts the measurement target.Note that the operating temperature limit is not the same as the allowable temperature limits of the grip, cord, and plug.Note that probes are more easily damaged at temperatures below 0°C, due to frost adhesion, reduced elasticity constant, and other factors.

About products made of polyimide

Some Anritsu Meter products are made of polyimide.Since polyimide may adversely affect humans, avoid using such products in applications where they may come into contact with food, internal organs, or bodily fluids.
